Description
The MA4PBL027 is a silicon beamlead PIN diode
fabricated with M/A-COM Technology Solutions
HMIC™ process. It features one silicon pedestal
embedded in a low loss, low dispersion glass which
supports the beam-leads. The diode is formed on the
top of the pedestal, and airbridges connect the diode
to the beam-leads. The topside is fully encapsulated
with silicon nitride and also has an additional
polymer layer for scratch and impact protection.
These protective coatings prevent damage to the
diode junction and air-bridge during handling and
assembly. The diodes exhibit low series resistance,
low capacitance, and extremely fast switching speed.
Applications
The ultra low capacitance, low RC product and low
profile of the MA4PBL027 makes it an ideal choice
for use in microwave and millimeter wave switch
designs, where low insertion loss and high isolation
are required. The low bias levels of +10 mA in the
low loss state and 0v in the isolation state allows the
use of a simple + 5V TTL gate driver. These diodes
can be used as switching arrays on radar systems,
high speed ECM circuits, optical switching networks,
instrumentation, and other wideband multi-throw
switch assemblies.
